NITED STATES PATENT OFFICE.

IRON BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 337,519, dated MarehQ, 1886.

Application filed September 24, 1885. Serial No. 178,109. (No model.)

To aZZ whom, it may concern:

Be it known that 1, ANDREW L. PRINGLE, of the city and county of San Francisco, and State of California, have invented an Improvement in Iron Bedsteads; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to that class of bedsteads which are made of iron; and my invention consists in the novel construction hereinafter eXplainecL'by which the union or joint at the corners of the bedstead is made.

The object of my invention is to simplify the construction of the bedstead, and at the same time to strengthen it and lessen the cost.

Further objects are cleanliness and safety, the latter being of importance by reason of the nature of the use of such bedsteads, they being employed in insane-asylums, where the cunning of the occupant may lead him to take the bedstead to pieces, provided this can easily be done.

Referring to the accompanying drawings, Figure 1 is a perspective view of one corner of my bedstead. Fig. 2 is a vertical section of same.

These iron bedsteads are usually made of gas-pipe, constituting the vertical end frames and the lateral and longitudinal horizontal frames, and angle-iron constituting the horizontal and transverse frames to which.the woven-wire mattress is clamped.

A is a T-coupling, which receives the pipe B of the longitudinal horizontal frame, the pipe C of the head or foot portion of the vertical frame, and the pipe D of the leg portion of said vertical frames. All of these pipes are screwed into the T-coupling, the two former being set up very tight, as they are designed to be practically permanent, while the latter or leg pipe is screwed in, so that it can be removed when desired.

E is the angle-iron strip, having secured to it by bolts e the clamping-plate F, which secures the woven-wire mattress. (Not here shown.) The angle-iron strip E is thus secured. Its horizontal portion is cut off, and

fits snugly against the side of the T-coupling A. Its vertical portion is continued back of the T coupling, and lies against it, being preferably curved slightly at its extreme end to make a neat joint. A bolt, G, passes through this portion of the angle-iron, through a washer, between its inner surface and the T-coupling, and into said coupling, where it receives a nut, g.' In putting this bolt in place, the pipe D is of course removed, to afford access to the interior ot'the coupling, and when said pipe is replaced it will be seen that the nut g is effectually concealed, and cannot be reached by the exercise of any ordinary cunning of the insane. The bedstead is therefore safe and cannot be taken down.

Another advantage of my bed is, that the joints are perfectly tight, and no vermin can find lodgment, and because of the absence of small crevices and hidingplaces between the parts they will not be apt to settle, and can be reached easily if they do.

-I am aware that a bedstead has been constructed of tubular material, one end ofthe side rails being screwed to the head or foot post or standard, and the opposite end being inserted into a tube or sleeve which projects from said post or standard. I am also aware that setscrews have been passed through openings in said standards and secured by nuts formed in the ends of the said rails, whereby greater rigidiry is secured, and such construction I therefore do not broadly claim as my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In an iron bedstead, the combination of the' T-coupling A, the pipes 13 C D, screwed into the coupling, thelatter pipe being readily removable, the angle-iron strip E, having its horizontal portion abutting against the side of the coupling and its vertical portion passing behind it, the bolt G, passing through the angle-iron strip and the back of the coupling, the nut g on the inner end of the bolt within the coupling, and the clamp-plate F, substan tially as herein described.

In witness whereof I have hereunto set my hand.

ANDREW L. PRINGLE.
